Move app to system partition

* As @fryevia discovered, there will be an error when
sdk_version doesn't exist in device tree (vayu in this case)

* error: packages/apps/SoftAPManager/app/src/main/Android.bp:1:1:
  module "SoftAPManager" variant "android_common":
  sdk_version: sdk_version must have a value when the module is
  located at vendor or product
  (only if PRODUCT_ENFORCE_PRODUCT_PARTITION_INTERFACE is set).

* Therefore, moving it to system would be the best selection for
  device trees which don't include "sdk_version".
